MEANS FOR GENERATING ELECTRICITY FROM CAR-WHEEL AXLES.

SPECIFICATION forming part of Letters Patent No. 564,336, dated July 21,1896.

Application filed April 23, 1896.

To all whom it may concern.-

Be it known that I, MORRIS MOSKOWITZ, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Means for GeneratingElectricity from Oar-Wheel Axles; and I do here by declare the followingto be a full, clear, and exact description of the invention, such asWill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention has reference to a novel arrangement of a dynamo securedto a cartruck and a means for operatively connecting the dynamo with acar-wheel axle of the truck to drive the dynamo.

The invention therefore has for its primary object to provide a dynamoto be secured on the car-truck, an operating'device arranged and securedupon the car-wheel axle, and a mechanical means, also secured on thecartruck, provided with an operating-shaft arranged in adjustablebearings to automatically maintain the proper tautness of the beltconnecting the device on the oar-wheel axle with said mechanical means,and also of the belt which connects said mechanical means with the saiddynamo.

The invention therefore consists in the novel arrangements andcombinations of parts to be hereinafter fully described, and finallyembodied in the clauses of the claim.

The invention is illustrated in the accompanying sheets of drawings, inwhich Figure 1 is a sectional view of portions of a railway-car and oneof its car-trucks, said view also illustrating in side elevation oneform of dynamo, a bracket provided with automatically adjustablebearings having a shaft rotatively arranged therein, and a pulley-wheelon said shaft, a pulley-wheel on the car-Wheel axle, andconnecting-belts for operating, first, said pulley-wheel on the shaft inthe adjustable bearings, and, secondly, the dynamo from a secondpulley-wheel on said shaft in the adjustable bearings.

plan view of a portion of the car-truck and of the dynamo and itsoperating mechanism. Fig. 3 is a vertical section taken on line a; inFig. 2 when looking in the direction of the arrow at. Fig. lis aperspective view of one of the brackets provided with the herein-'above-mentioned adjustable bearing.

Similar letters of reference are employed in all of the above-describedviewsto indicate corresponding parts.

In said drawings, Aindicates the car-truck; a, the equalizing-bars; a,the cross-beams at the ends of the truck, and a are other crossbeamswhich are connected with the equalizing-bars a in any well-known manner.

As will be seen more especially from Figs. 1 and 2, the dynamo B, whichmay be of any of the well-known forms of construction, is supported in asuitable frame or bracket a which is secured to the end beam a by meansof suitable bolts 00 or in any other suitable manner. The armature-shaftb of said dynamo is supported and rotates in suitable brackets orsupports a and aflwhich are secured to the, end beam at of the cartruck,as clearly illustrated in Figs. 2 and 3. Said armature-shaft b isprovided with a pulley-wheel b, and b are the circuit-Wires, whichextend from the dynamo to suitable lamps b or other electricaltranslating devices on or in the body of the car.

Upon the car-Wheel axle (t7 I have arranged a pulley-wheel c, which ispreferably made in halves and is provided with suitable flanges o andbolts 0 whereby the two halves can be secured together and firmlyclamped in the desired position upon the car-wheel axle, as will beclearly evident.

Secured directly to the cross-beam o of the car-truck A are a pair ofbrackets D, as will be clearly seen from an inspection of Figs. 1, 2,and 4, each bracket consisting, essentially, of a main or body portioncl,having the grooved part d, provided with a hole or perforation dsubstantially as illustrated in Fig. 4. Extending at a right angle, orapproximately so, from the back of said portion d is a lip orprojection(1 provided with a hole 01 whereby said brackets D can be made toembrace the said cross-beam a on two sides and can be firmly securedthereto by means of suitable bolt-s, as clearly represented in Fig. 1,but said bracket D may be otherwise secured to said crossbeams, as willbe evident.

At or near the top of the body portion (Z of each bracket D are a pairof lugs or cars 61'', provided with holes or perforations for suitablepins or bolts cl, and pivotally arranged on said pins or bolts cl, andbetween the said ears or lugs (1", are certain swinging bars or platesc,each plate being provided with a bearin g e, in which is rotatively journaled a shaft 6 provided with a pulley-wheel c between said bracketsD and a second pulley vheel c at or near the one end of said shaft,substa11- tially as illustrated in said Fig. 2. Said pul' ley-wheel c isin alinement with the pulleywheel 0 upon the car-wheel axle, and a belte is employed which passes over said pulleywheels and thereby causes therotation of said shaft 6 when the car-wheel axle is operated. Thepulley-wheel e on said sh aft 6 is in alinement with the p ulley-wheel bon the armatureshaft b of the dynamo, a belt 0 being passed over saidpulley-wheels, substantially as shown, and thus it will be evident thatthe dynamo can in this manner be operated from the rotating car-wheelaxle.

As will be seen from Figs. 1 and 4, each body portion cl of saidbrackets D is provided with a forwardly-extendin g arm d having anupwardly-projeeting end piece (Z In order to maintain both of said beltsc and e taut, to properly operate the dynamo, I have providcd theupwardly-projecting end piece d and the swinging plates 6 of eachbracket D with suitable teats or holding-lugs d and 6 respectively, andupon these I have arranged the ends of a coiled spring 6 substantiallyas illustrated in said Fig. 4:. hen the belts e and c are first placedover their respective pulley-wheels,then the said springs c arecompressed and said swingingv plates or bars 0 made to inclineforwardly, which readily enables the placing of the two belts over therespective pulley-wheels, but after both belts have been properlyarranged over their pulley-wheels then the said plates or bars c arereleased and the coils of the spring 6 will then tend to resume theirnormal inoperative positions, and the result is that both belts will atall times be maintained taut and any vibratory motion of the car-wheelaxle in its bearings will be compensated for by the spring'actuated barsor plates 6, whereby an operative connectionfor driving the dynamo,arranged on a car-truck, from a car-wheel axle will be the result.

The operation of the several parts is practical and in construction verysimple, and a noiselessly operating mechanism has thus been provided foroperating a dynamo from a rotating car-wheel axle. Of course it will beunderstood that I may use in connection with the said dynamo and itscircuits any of the well-known forms and constructions of pole-changers,acting automatically or otherwise, whereby the current generated by thesaid dynamo can be made to travel in either direction, according to thedirection of the travel of the car.

Having thus described my invention, what I claim is 1. The combination,with a car-whcel axle and truck-frame, of a dynamo on said frame, apulley-wheel on said car -wheel axle, a bracket D on said frame, aswinging bar or plate 6 on said bracket, a shaft a", pulleywheels c andc on said shaft, and belts e and 6 arranged substantially as and for thepurposes set forth.
